  1. 1. Immunoecology of the Great Snipe (Gallinago media) : Mate Choice, MHC Variation, and Humoral Immunocompetence in a Lekking Bird

    Författare :Robert Ekblom; Jacob Höglund; Mats Grahn; Scott V. Edwards; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Behaviour; Major histocompatibility complex class II B; Sexual selection; Evolution; Leks; Biologi; Biology; Biologi;

    Sammanfattning : At the centre of the vertebrate immune system is a group of proteins called MHC (major histocompatibility complex) molecules. These function in self – non self recognition and activation of the immune defence against intruding parasites and pathogens. LÄS MER

  3. 2. On the Effects of Blood Parasites in Wild Birds

    Författare :Peter Halvarsson; Jacob Höglund; Staffan Bensch; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Atoxoplasma; avian malaria; coccidia; Gallinago media; Haemoproteus; Leucocytozoon; parasite prevalence; Passer montanus; Plasmodium; recapture mod-els; survival; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

    Sammanfattning : Coccidian and haemoatozoan parasites are commonly occurring endo-parasites in wild birds and prevalence can vary among species and populations. In addition to prevalence studies, parasites are often used to investigate effects on life history traits. LÄS MER

  4. 3. Population Genetic Analyses of Natal Dispersal and Substructure in Three Bird Species

    Författare :Tobias Sahlman; Jan Ekman; Jacob Höglund; Ben J. Hatchwell; Uppsala universitet; []
    Nyckelord :Ecology; Perisoreus infaustus; Gallinago media; Lagopus muta; relatedness; philopatry; biased dispersal; phylogeography; microsatellite; mitochondrial DNA; Ekologi;

    Sammanfattning : Genetic variation within and among populations is a result of past and ongoing processes. Among the most important of such processes are dispersal, habitat fragmentation and selection. This thesis use neutral genetic variation as a tool to investigate these processes in three bird species. LÄS MER

  7. 5. Development and Application of Genomic Resources in Non-model Bird Species

    Författare :Biao Wang; Jacob Höglund; Christopher Wheat; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; genome; transcriptome; next generation sequencing; non-model species; bioinformatics; reference guided assembly; RNA-Seq; comparative genomics; gene expression; major histocompatibility complex; single nucleotide polymorphism; microsatellite; Biologi; Biology;

    Sammanfattning : Understanding the genetic basis of biological processes is a fundamental component of modern ecology and evolutionary biology studies. With the recent advent of next generation sequencing (NGS) technologies, it is now possible to perform large genome and transcriptome projects for ecologically important non-model species. LÄS MER
